As of late, adidas Originals has strongly hinted at a new Yeezy Boost release. The most recent drop was a "Pirate Black" 350 re-stock back in Feb., so sneakerheads are eagerly waiting to find out what's next. Often, Kanye West himself foreshadows the next colorway / model by wearing it out, If that's the case, the Grey/Gum 750, Black/White Striple SPLY 350, Black Translucent 350 and all-white 350 could all be in play.

While we stand by for word from adidas, here's a rundown of 12 pairs of Yeezy Boosts that have surfaced over the last year, but haven't been released. There's been debate over the name of the "evolved" 350 model, some referring to it as the rumored 550. Until something else is confirmed, we'll stick with 350. See the model in several new colorways, along with the 750, below.
